I have not planned on a cage, but you never know. So far just a roller cam 5.0 with the same treatment as the hotrod $350 junkyard motor, although I would also like to move it up to a 347 in a couple of years assuming I don't break it first. Trans T-10 close ratio four speed, and rear is a Ford 8.8 with 3.73:1 gears and a trac lok. Disc brakes all around with the old four piston Kelsey Hayes style front calipers. I'll probably be real lucky if I get it into the 12's with this recipe, so I don't think I need a cage just yet, although safer is safer if that makes any sense. One thing I do want to do is upgrade to a colapsable steering column as soon as I can. I figure a head on is more likely than a roll over on the street.
